If anyone has any objections, please let me know. ------------------ From: Trond Myklebust commit 5694c93e6c4954fa9424c215f75eeb919bddad64 upstream. Aside from making it clearer what is non-trivial in create_client(), it also fixes a bug whereby we can call free_client() before idr_init() has been called.
